Maths Paper 1 0.0 / 5 ? MathematicsPaper 1GCSEAQA Created by: annelister12Created on: 15-05-22 11:17 How do you work out g⁻¹(x)? (let's say that g(x) = 4x - 3) g(y) = x 4y - 3 = x 4y = x + 3 y = x + 3 divided by 4 Hence g⁻¹(x) = x + 3 divided by 4 1 of 5 If the co-efficient is more than 1, how do you factorise? Example: 9x²-30x+25 9x²-30x+25 9x²-15x-15x+25 3x(3x-5)-5(3x-5) (3x-5)(3x-5) 2 of 5 a⁻ᵐ = ? a⁻ᵐ = 1 divided by aᵐ 3 of 5 a¹/² = ? √a 4 of 5 aⁿ/ᵐ (ᵐ √ a)ⁿ 5 of 5
